Chromosomal manipulation in Senegalese sole (Solea senegalensis Kaup, 1858): induction of triploidy and gynogenesis.
Article in Journal of applied genetics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In this study we have developed protocols for induced triploidy and gynogenesis of Senegalese sole (Solea senegalensis), a promising flatfish species for marine aquaculture, in order to: 1) identify the sex-determination mechanism; and 2) to improve its production by generating a) sterile fish, avoiding problems related with sexual maturation, and b) all-female stocks, of higher growth rate. Triploidy was induced by means of a cold shock. Gynogenesis was induced by activating eggs with UV-irradiated sperm, and to prompt diploid gynogenesis, a cold-shock step was also used. Ploidy of putative triploid larvae and gynogenetic embryos were determined by means of karyotyping and microsatellite analysis. Haploid gynogenetic embryos showed the typical "haploid syndrome". As expected, triploid and gynogenetic groups showed lower fertilization, hatching, and survival rates than in the diploid control group. Survival rate, calculated 49 days after hatching, for haploid and diploid gynogenetic groups was similar to those observed in other fish species (0% and 62.5%, respectively), whereas triploids showed worse values (45%). Sex was determined macroscopically and by histological procedures, revealing that all the diploid gynogenetic individuals were females. In conclusion, we have successfully applied chromosomal-manipulation techniques in the flatfish species Senegalese sole in order to produce triploid, haploid, and diploid gynogenetic progenies.
